Available in PDF, EPUB and Kindle. Book excerpt: Vapor-liquid equilibrium (VLE) data of solutions are necessary for the design of distillation and absorption processes. VLE exhibits various characteristics depending on the type of solution. In the case of nonideal solutions, an azeotropic mixture is formed which cannot be separated by ordinary distillation. The mixture must be separated by adding a third component, called an entrainer, which has the capability of breaking the azeotropic point. In most cases, a volatile component is employed as an entrainer for an azeotropic mixture. However, salt is also effective in breaking the point; this is called the salt effect on VLE. Much has been observed on salt effect, however very few commercial distillation plants use this method. This book aims to cover all reported data found in journals on salt effect on VLE. Prediction methods for VLE at low and high pressures for systems composed of volatile substances are used routinely, However, no method to predict the salt effect on VLE is in use, because salts show entirely different behavior from volatile substances. A method to predict salt effect based on preferential solvation was reported by the author in 1976.30 systems were examined and the formation of preferential solvates between the salt and one of the volatile components was shown. Continuing the work, the formation of preferential solvates for almost all salt effect data has been examined. As a result of this work, it has been found that preferential solvates are formed without exception. In this volume, the preferential solvation numbers determined by least squares method are shown by processing the data of salt effect on VLE.

Download or read book Vapor Liquid Equilibria Using Unifac written by Aage Fredenslund and published by Elsevier. This book was released on 2012-12-02 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vapor-Liquid Equilibria Using UNIFAC: A Group-Contribution Method focuses on the UNIFAC group-contribution method used in predicting quantitative information on the phase equilibria during separation by estimating activity coefficients. Drawing on tested vapor-liquid equilibrium data on which UNIFAC is based, it demonstrates through examples how the method may be used in practical engineering design calculations. Divided into nine chapters, this volume begins with a discussion of vapor and liquid phase nonidealities and how they are calculated in terms of fugacity and activity coefficients, respectively. It then introduces the reader to the UNIFAC method and how it works, the procedure used in establishing the parameters needed for the model, prediction of binary and multicomponent vapor-liquid equilibria for a large number of systems, the potential of UNIFAC for predicting liquid-liquid equilibria, and how UNIFAC can be used to solve practical distillation design problems. This book will benefit process design engineers who want to reliably predict phase equilibria for designing distillation columns and other separation processes.

Book excerpt: Thermodynamic data form the basis for separation processes used in different fields of science and industry, from specialty chemicals to foods and pharmaceuticals. One obstacle to developing new production processes, products, or optimization is the lack, or inaccessibility, of experimental data related to phase equilibrium. Access More Than 1200 Data Sets, Including 810 Binary Systems, 325 Ternary Systems, and 25 Quaternary (or Higher) Systems The CRC Handbook of Liquid-Liquid Equilibrium Data of Polymer Solutions provides a thorough and up-to-date compilation of experimental liquid-liquid equilibrium (LLE) data and their original sources. Arranged in a consistent format, the handbook provides convenient access to cloud-point and coexistence data as well as upper and lower critical solution temperatures and important demixing data for each system. An Excellent Companion to the Author’s Previous Collections of Thermodynamic Data! While the author’s previous data compilations center around specific types of polymer systems, Wohlfharth’s latest work distinguishes itself by focusing instead on representing LLE data for all types of polymer systems in a single source.

Download or read book The Physical Basis of Thermodynamics written by Pascal Richet and published by Springer Science & Business Media. This book was released on 2001-08-31 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Given that thermodynamics books are not a rarity on the market, why would an additional one be useful? The answer is simple: at any level, thermodynamics is usually taught as a somewhat abstruse discipline where many students get lost in a maze of difficult concepts. However, thermodynamics is not as intricate a subject as most people feel. This book fills a niche between elementary textbooks and mathematically oriented treatises, and provides readers with a distinct approach to the subject. As indicated by the title, this book explains thermodynamic phenomena and concepts in physical terms before proceeding to focus on the requisite mathematical aspects. It focuses on the effects of pressure, temperature and chemical composition on thermodynamic properties and places emphasis on rapidly evolving fields such as amorphous materials, metastable phases, numerical simulations of microsystems and high-pressure thermodynamics. Topics like redox reactions are dealt with in less depth, due to the fact that there is already much literature available. Without requiring a background in quantum mechanics, this book also illustrates the main practical applications of statistical thermodynamics and gives a microscopic interpretation of temperature, pressure and entropy. This book is perfect for undergraduate and graduate students who already have a basic knowledge of thermodynamics and who wish to truly understand the subject and put it in a broader physical perspective. The book is aimed not at theoretical physicists, but rather at practitioners with a variety of backgrounds from physics to biochemistry for whom thermodynamics is a tool which would be better used if better understood.
